CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/779,076 filed Jan. 31, 2020. The disclosure of which are hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTIVE FIELD

The present invention is directed to a portable, self-contained, toothbrush with internal water supply. The toothbrush of the present invention allows a user to brush their teeth on-the-go, even when there is no available external water source or receptacle to expel the spent water and toothpaste when the user is finished brushing.

Brushing one's teeth is needed for three main reasons: 1) to maintain healthy teeth and gums; 2) to eliminate food particles that may be visible to others; and 3) to maintain fresh breath. Toothbrushing is easier when at home or at the office as there is access to a toothbrush, toothpaste, water and a sink. When away from home or the office, users currently have to make do with other, suboptimal options.

A complete toothbrushing experience includes all the following steps:

-   -   Application of toothpaste on a toothbrush;     -   Wetting of toothbrush;     -   Mechanics of brushing;     -   Rinsing out toothpaste with water; and     -   Expelling rinse water and excess toothpaste.

Currently there is no single, self-contained apparatus that enables all of the above steps for full toothbrushing. The complete toothbrushing experience of the present invention provides a portable solution to enable users to perform all the tasks necessary to create, not just replicate, full brushing of teeth.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

The following detailed description of the exemplary embodiments refers to the accompanying FIGURES that form a part thereof. The detailed description provides explanations by way of exemplary embodiments. It is to be understood that other embodiments may be used having mechanical and electrical changes that incorporate the scope of the present invention without departing from the spirit of the invention.

The present invention relates to a portable toothbrush having an internal water source that allows a user to brush his or her teeth while away from a bathroom, sink or other external water source. The embodiments described herein are exemplary embodiments and are not intended to limit the scope of the inventions claimed. For example, the toothbrush of the present invention preferably has a water source and a storage receptable for suctioning waste or rinse water from the user's mouth back into the storage receptacle for disposal after use. The toothbrush of the present invention can be automatic (electric motor or pump) or manual. The toothbrush can be a one-time use toothbrush or multiple-use.

FIG. 1 illustrates one embodiment of the toothbrush device of the present invention. In this embodiment, the toothbrush 10 of the present invention is comprised of a base 12, water controller 14, suction controller 16, toothpaste controller 18, head ejector 20, base gasket 22, water supply receptacle or water source 24, waste receptacle or storage area 28, toothpaste receptacle or storage area 26, head gasket 30, removable head 32, fluid hole or opening 34, cover 36, bristles 38, and small electric motor or pump 40.

In the embodiment of FIG. 1, there are three internal tubes (shown generally at 41) that connect each of the receptacles or storage areas to the toothbrush head in order to accomplish the functions of dispensing water from the water source, dispensing toothpaste to the bristle area and suctioning rinse material from the user's mouth to the waste receptacle. Receptacles can be storage areas or capsules within the toothbrush of the present invention. For example, in one embodiment, the capsules, receptacles or storage areas are individual pipettes, bellows or other suctioning device or syringe (shown generally at 28), with a compressible end that can be compressed to force a substance out of the other end of the storage area or it can be expanded (from a compressed state) to suction in substance into the storage area. In one embodiment, the storage receptacles can be removed for refill and/or cleaning. At purchase, the packaged toothbrush is provided with seals over the openings in the pipettes that can be easily punctured before use to allow access to the pipette storage areas.

The base is preferably constructed of metal or plastic and preferably does not require constant cleaning as it is the portion that is attached to the removable head portion that contains the components that require intermittent cleaning (at least for the multi-use embodiment, the single-use embodiment can be discarded after one use). In the embodiment of FIG. 1, the base is preferably comprised of three thumb switch controllers or actuators: one switch 14 for controlling the amount and force of water flow from the water supply receptacle to the fluid opening (for wetting and rinsing purposes), one switch 16 for controlling the suctioning of rinse water and or excess toothpaste from the user's mouth to the waste receptacle, and one switch 18 for controlling the dispensing of toothpaste from the toothpaste receptacle to the fluid opening.

In one embodiment, the toothbrush of the present invention is adapted so that the user can replenish the toothpaste and water supply receptacles. The head portion of the toothbrush preferably has a fluid hole that allows for clean rinse water to flow from the water supply to the bristles and to the user's mouth and for used rinse (used) water and toothpaste from the user's mouth to flow to the waste receptacle. It is also appreciated that the switches can be buttons, tabs, or levers for controlling the stated functions.

The head ejector is preferably a pressable button that ejects the removable head from the base. In this embodiment, the head portion is removable and disposable, but it is appreciated that the head portion can also be integral with the base portion.

The base gasket preferably provides a water-tight seal between the base portion and removable head. The head gasket completes the water-tight seal with the base. In one embodiment, the toothbrush head portion is adapted with a removeable cover to keep the bristles clean and dry after use.

In the embodiment shown in FIG. 1, a small motor or pump contained within the base portion is operationally connected to the water supply, and toothpaste supply to dispense water or toothpaste to the head bristle portion. For example, a vibrating mini-disc motor or mini pump motor can be used with the toothbrush of the present invention. The motor or pump forces water to the bristle area or user's mouth, and can be switched to suction used rinse water from the user's mouth into the waste storage area or receptacle after toothbrush use. It is appreciated that the toothbrush in this embodiment also has an internal battery for supplying power to the motor or pump.

In the embodiment of FIG. 1, the toothpaste can be manually dispensed via a slider switch or mechanism or it can also be dispensed using an internal motor or pump. It is also appreciated that the embodiment having the electric motor or pump can be configured with a removable head portion that may be a one-time disposable head portion or a multi-use disposable head portion. If a one-time use, toothpaste (or other teeth cleaning substance) may be placed, pre-packaged, onto the bristles instead of having a toothpaste receptacle and controller for dispensing toothpaste.

In the embodiment of FIG. 1, an internal pump or motor can be operationally connected to the waste supply receptacle for causing the suctioning of waste material from the user's mouth into the waste storage area. The internal pump or motor can be separate from, or the same as, the pump and motor operationally connected to the water receptacle and the toothpaste receptacle.

The following steps describe the process for using the toothbrush of the present as shown in FIG. 1:

-   -   1. User removes head portion from a resealable plastic pouch;     -   2. User snaps the head portion to the base portion causing a         seal over the water supply and toothpaste receptacles to         puncture;     -   3. User places the head portion in mouth and closes lips;     -   4. User dispenses toothpaste into the mouth by engaging the         toothpaste controller;     -   5. User presses the water supply controller causing a stream of         water to flow through fluid hole into the user's mouth, wetting         bristles and toothpaste;     -   6. User brushes teeth, keeping mouth closed to secure liquids;     -   7. User presses suction controller to cause fluids to be sucked         from the user's mouth into the waste receptacle;     -   8. User may continue Steps 5 through 7 to rinse mouth and         suction;     -   9. When finished, user presses the head ejector button or switch         causing the head portion to separate from the base portion; and     -   10. The head portion may be placed back into pouch or otherwise         disposed of; or     -   11. The storage capsules may be removed from the head portion         and cleaned and refilled with water and toothpaste.

In an alternative embodiment, the dispensing of water and toothpaste, as well as the suctioning of rinse water from the user's mouth are all done manually, instead of using an internal motor or pump. In this embodiment, water is introduced by sliding a switch, which compresses the water in the water supply receptacle. In other words, in one embodiment, an internal bellows holding water can be forced out by compressing the end of the bellows. In this embodiment, rinse water can also be suctioned into the waste receptacle using compressed bellows. Sliding a switch in a direction away from the head portion allows the bellows to expand, creating the necessary suction.

In this alternative manual embodiment, toothpaste can come pre-supplied on the bristles using a disposable single use head portion or unit. In such an embodiment, water from the water supply receptacle can be dispensed onto the bristle area or the user's mouth to wet the bristles and the supplied toothpaste.

The following steps describe the process for using the manual toothbrush of the present invention (alternative embodiment):

-   -   1. User removes the head portion from resealable plastic pouch;     -   2. User snaps the head portion to the base portion causing a         seal over the water supply portion to puncture;     -   3. User places the head portion in the user's mouth and closes         lips;     -   4. User engages the water controller switch causing stream of         water to flow through the fluid hole or opening into mouth;     -   5. User brushes teeth, keeping mouth closed to secure liquids;     -   6. User engages the suction controller to cause fluids to be         suctioned into the waste receptacle;     -   7. User may continue Steps 4 and 6 to rinse mouth and suction         repeatedly;     -   8. When finished, the user presses the ejector switch causing         the head portion to separate from the base portion; and     -   9. The head portion may be placed back into pouch or otherwise         disposed of.
